The nature of electromagnetic and electromechanical processes. Conversion of electrical energy into mechanical energy and vice versa. Transformers, their working principles, main types and areas of use. Ideal transformer and transformer equivalent circuits. Types of electrical motors, construction, operating principles, characteristics, start-up and adjustment. Generators.

The course is aimed for clarification of physical processes, which are the basis of working principles of electrical transformers and motors, as well as giving an overview of their types, construction, operations, areas of use, and technical parameters.

A student:
1) has an understanding of electrical machines and their classification;
2) has an understanding of the most common static electrical machines (transformers) and the most important physical processes;
3) has an understanding of types of rotating DC machines, their structure and operation;
4) has an understanding of types of rotating AC machines, their structure and operation.
